Extra line error running npm install

I forked the repo and ran npm install and got this error 
```
shufflejs-react/src/SortFilter/Core.js 77:1  error  More than 1 blank line not allowed  no-multiple-empty-lines
```
Node Version: 12.14.1
Operating System: Mac OS Mojave

I removed the extra line and ran npm install again and it worked.
My bad, I copied the wrong line..
